[The clinical study on labor pain relief using two kinds of segmental block anesthesia]
Objective:
To study the pain relief effectiveness of combined subarachnoid peridural segmental block and simple peridural anesthesia, and their influences on the mothers and the infants.
Methods:
100 pregnants women were administered combined subarachnoid and peridural segmental block during labor and delivery (study group). 40 pregnant women received simple peridural anesthesia (control group). The degree of labour pain, side effects, labor course, the mode of delivery and the incidences of postpartum hemorrhage, fetal distress and neonatal asphyxia were observed in two groups respectively.
Results:
The pain relief effect in the study group was much better than that of the control group (P < 0.01). There were no significant differences of the mean time of labor course and the mode of delivery between the two groups (P > 0.05). The incidences of postpartum hemorrhage, fetal distress and neonatal asphyxia were similar (P > 0.05).
Conclusion:
The analgesic delivery of combined subarachnoid and peridural segmental block is safe and effective, which has no influences on the labour course and the mothers and infants. Its pain relief effectiveness is more positive and satisfactory than that of simple peridural anesthesia. We suggest that it should be performed in the medical units under optimal conditions.
